WINDLASS AND CAPSTAN AND MEANS FOR DRIVING SAME` SEECIFIGATION forming par?. of Letters PatentNo. 695,994, dated March 25, 1902. Application filed April 12, 1901. Serial No. 55,482. (No model.)

Be it known that I, JACOB R. ANDREWS, a citizen of the United States, residing at Bath, Maine, have invented certain new and useful Improvements Connected with and Relating to XVintllasses and Oapstans and the Means for Driving the Same, of which the following is a specification.

My invention relalcs to poweroapsta ns, the object of it being to simplify the construction and afford an arrangement by which two power-capstans may be driven from the same worm-gear which is placed upon the crankshaft of the engine or engines. In this way I provide a pair of eapstans placed at convenient distances convenientlyadapted to the work which they have to perform upon the ship and at the same time simplify the construction, so that the number of parts is less than that in any apparatus of this class so far as I am aware.

My invention is illustrated in the accompanying drawing, in which the ligure is a plan view showing the relative arrangement of the parts.

In the 'drawing' the engines, which are Vertically arranged, are shown at A. They are connected toahorizontal crankshaft B, which at its end is provided with a worm u. The

shafts of the two capstans, which are alike, are vertically arranged to carry capstans on their upper ends and turn in suitable bearings. They are shown at B, andl each has keyed to it worm-gears c. These are arranged on opposite sides of the wormwhich is upon the crank-shaft, and each is operated by this same worm. The parts are perfectly balanced, and there is but one worm-shaft, which is at the same time a crank-shaft, and no bevel-gears are required, while the arrangement affords the convenience of two capstans without any additional driving mechanism excepting the worm upon the additional crank-shaft.

I am aware that it is not new to drive drums or shafts by worm-gears, and I am also aware that it is not new to place a worm upon a crank-shaft, but

What I claim as my invention is- The horizontal crank-shaft connected with suitable driving-engines and provided with a Worm in combination with wormgears C on vertical eapstan-shafts, one upon each shaft, the said worm-gears being arranged one on each side of the worm, and meshing therewith whereby the same worm upon the crankshaft operates a pair of capstans, all the parts being constructed and arranged substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB1 R. ANDREWS.
